The Specialist's Opinion on the 11x12 ft Anthracite Gray Metal Garden Shed FIRST - X-METAL

X-METAL's FIRST collection now includes this metal garden shed with a surface area of 11x12.5 ft., making it 129.17 ft². The quality/surface/price ratio are unbeatable!

The First metal garden shed collection from X-METAL combines simplicity with design. Its pure anthracite look will harmonize wonderfully with your exterior design, whether it is modern or rather classic. Inside, you will find many possibilities to organize your things different way thanks to its size.

Its design with solid metal beams means it is pretty resistant to bad weather, and in particular has good resistance to snow since it can hold a maximum load that can reach 14.33 lbs/ft². X-METAL's First collection sheds are delivered with stainless steel screws and bolts, which will prevent rusting and degradation of the hardware, as is often the case with low-cost metal garden sheds. The galvanized steel panels are easy to handle for assembly which promotes easy construction. They are covered with a 4 coat paint for durability!

The ventilation grills are located on the roof, ensuring a renewal of air inside even when not opened for a long time.

This 11x12.5 ft garden shed from X-METAL's First collection has a 10-year warranty.
